Mark Anthony Drunk Dials J.Lo, The Do's and Don'ts of Breakups

Letting go isn't easy. Marc Anthony is apparently begging Jennifer Lopez back, going so far as to drunk dial her. Is he Facebook stalking her, too? If so, it must've been painful to see how many peopled liked: "Jennifer Lopez is now single."

An insider tells Us Weekly that Lopez has been "harassing" J.Lo, asking her to reconsider the divorce.

"He calls her nonstop," says the insider. "Marc is constantly harassing her and doesn’t think she'll go through with the divorce.

Anthony's camp is denying any of this. The two are remaining amicable, though. Earlier this month, the pair was seen in Southhampton, NY spending time with their 3 year-old twins, Max and Emme.

I didn’t think it was possible, but I actually feel an inkling of pity for the guy. But from Lopez's side, it seems pretty definite that this is the end. And if so, Marc is breaking the number one breakup rule: Don't call the ex!

Here are some other breakup Do's and Don'ts, and the celebrities who learned them first hand.

Don't jump from one bed to another. They say the best way to get over someone is to get under someone else. While some people swear by this, it takes some finesse to pull off a good, clean rebound. You've either got to 1) make it just about the rebound; or 2) really be sure you're ready for another relationship that quick. You don't want to run the risk of going through a slue of sub-par relationships for years trying to get over one bad breakup. Not that ahem I would know anything about that. But take a look at Jesse James. As soon as he left Sandra Bullock, he was engaged to Kat Von D. And how did that end up? Two broken hearts and one really, really ugly tattoo.

Don't dwell. When you're mourning the loss of your significant other, it's easy to remember only the good things about your relationship. After all, you miss them! But ya broke up for a reason. Think about that. And don't you remember that one really annoying, disgusting habit or trait they had? Yeah, write that down. When your heart is breaking, take a look at it. Reading "wiped boogers on bathroom wall" will really mend a broken heart. That being said, you don’t want to trash talk, either. Camille Grammer talking about Kelsey's small dong isn't attractive. And it shows she hasn't moved on.

Do annoy the hell out of your friends. They're your friends, that's what they're for. Tell them every detail about what you're going through. Call them in the middle of the night just to say, "I just realized I'm gonna be okay." They'll be pissed, but you can apologize when you're not depressed anymore. Family is good, too. Eva Longoria told Hollyscoop: "Every time I go through a tough time I just lean on my family."

Do start a project. If anything, it gets your mind elsewhere. But you also just might get a critically acclaimed album out of it. Adele's album, 21 was inspired by the breakup of an ex. "I was really gutted that we didn’t manage to recover from our kind of boredom of each other,” the singer said. Throwing your energy into something is a good way to move on. But you might consider working on a project that isn't related to your ex at all.
